GEODESIC DOME ROOF

The HMT Geodesic Dome features a clear-span, all-aluminum, lightweight, corrosion-resistant structure which sets a new standard for performance in aluminum geodesic domes.

HMT’s unique overlapping-panel design and attention to details at critical locations all result in a cost-effective solution that provides superior protection of your stored product.

The HMT Geodesic Dome can be installed in-service and its superior design was developed under the guidance of API 650, appendix G and AWWA D-108.

Key benefits: Key design features: The HMT Geodesic Dome’s advanced t
Batten bar and gasket assembly completely technology provides excellent benefits. Here’s encapsulate panel edges for unparallelled how: sealing Most effective leak-protection solution— t
Overlapping panels ensure additional Engineered for maximum weather-tightness for protection against weather both new tanks and retrofits t
Hub designed with three levels of sealing to Low maintenance — Aluminum alloys are ensure maximum leak protection corrosion resistant and don’t require painting like steel fixed roofs t
Hub can be easily removed for inspection or Emissions reduction — reduces wind-induced adjustment of IFR support chains vapor loss, aids in odor control and provides t
Options for fixed or sliding rim connections significant emission credits; for light products such as gasoline, a dome installed over an EFR t
Can easily handle the weight of suspended can cut emissions by over 90% aluminum internal floating roofs In-service installation — Can be erected on t
Industry-leading 3D design software for the ground beside the tank or on an EFR and maximum accuracy and shorter design time lifted into place Custom engineered— To accommodate a wide range of spans and loading conditions

Protecting your world, one tank at a time™ www.hmttank.com THE HMT GEODESIC DOME DESIGN HMT’s design incorporates features which dramatically Triple seal hub design improve upon existing technology. Here’s how: HMT’s uses best available technology with its three- Quality design details that result in part hub seal design. Silicone provides the first-level unsurpassed seal integrity protection. Secondly an annular angle allows 360˚ flashing protection with an internal gasket seal that HMT’s design incorporates many design details creates a third-level weather barrier in this design. which improve upon existing technology. The batten bar/gasket system fully encapsulates panel edges. The beams are designed with an extruded groove to receive fasteners without penetrating Primary through to the dome’s interior. Single web beam Seal Annular profiles reduce the overall weight of the structure Flashing Angle without comprimising structural performance. Double web beams can be provided when required. Ridges located on the top flange engage with sheeting for excellent mechanical sealing. This seal feature also protects gasket from product-side attack. This superior design was developed under Internal the guidance of API 650, Appendix G.3.2. Gasket Seal The hub design allows for easy removal of the cover for inspection and easy adjustment of internal floating roof support chains. Panel Edge Encapsulation Bolt Slot Other benefits and options Extruded Ridges t
Fixed and sliding connections available t
